Calculate the number of packs, the total quantity, and the total days supply for the following Rx: Albuterol 0.083% inh soln sig: 1 neb bid #50 refills ------------------------------------------------------------ The doctor has prescribed Albuterol Sulfate Inhalation Solution 0.083% with 25x3mL unit-dose vials. So, the pack has 25 vials (ampules) and each vial contains 3 mL of solution. The doctor has written 50 refills, that is, 50 vials. If 1 pack has 25 vials, then 2 packs have 50 vials. So, the pharmacist will dispense 2 packs. Now, we need to calculate the quantity to be dispensed. We know that each pack has 25 vials and each vial has 3 mL In turn, 25 vials * 3 mL = 75 mL So, each pack has 75 mL If 1 pack = 75 mL, then 2 packs = 150 mL So, the total quantity on the pharmacy computer will be 150mL The sig says: use 1 vial in nebulizer twice daily The patient will use 2 vials per day. Then, the total days supply will be 50 vials divided by 2 vials which is 25 days. |

Calculate the total quantity and the total days supply for the following Rx: Albuterol 2.5 mg/3 mL 1 breathing treatment q6-8h #25 vials ------------------------------------------------------------ The doctor wants the pharmacist to dispense 25 vials. The doctor has prescribed Albuterol Sulfate Inhalation Solution 2.5mg/3mL with 25x3mL unit-dose vials. This medicine can also be written as Albuterol Sulfate Inhalation Solution 0.083% This package of albuterol has 25 vials and each vial has 3 mL In this case, 1 vial = 3 mL and, therefore, 25 vials = 75 mL So, the total quantity to be dispensed is 75 mL The sig says: use one vial in nebulizer every 6 to 8 hours Now, we need to calculate the days supply. The pharmacist will use the maximum numbers of vials per day. We know that the patient may use one vial every six hours, that is, the patient may use one vial four times daily. In turn, the patient may use 4 vials per day. Then, the total days supply will be 25 divided by 4 which is 6 days. |

Calculate the total quantity and the total days supply for the following Rx: albuterol 0.083% neb 2 weeks supply one neb q8h x3days, then q6h prn wh ------------------------------------------------------------ The doctor has prescribed Albuterol Sulfate Inhalation Solution 0.083% with 25x3mL unit-dose vials. This medicine can also be written as Albuterol Sulfate Inhalation Solution 2.5mg/3mL This Albuterol box has 25 vials and each vial contains 3 mL of solution. The sig says: use one vial in nebulizer every eight hours for 3 days, then use one vial every six hours as needed for wheezing The total days supply is 14 days as stated by the doctor. The patient will use 1 ampule three times daily for 3 days, then the patient will use 1 ampule four times daily for 11 days. So, the patient will use (1 * 3 * 3) vials, then the patient will use (1*4*11) vials. In other words, the patient will use 9 ampules, then the patient will use 44 ampules. So, the patient will use (9 + 44) ampules, that is, 53 ampules. We know that the package has 25 vials. The number of packages the patient needs will be 53 divided by 25 which is 2 packages. Now, we need to calculate the total quantity in milliliters. We know that the patient needs 2 packages. 1 package = 25 vials and, therefore, 2 packages = 50 vials We know that 1 vial = 3 mL and, therefore, 50 vials = 150 mL So, the total quantity to be reported on the computer system is 150mL On the other hand, some pharmacists may dispense Albuterol Sulfate Inhalation Solution 0.083% with 60x3 mL unit-dose vials. This Albuterol box has 60 vials. In this case, the pharmacist would dispense one box of 60 vials. Now, the box has 60 vials and each vial has 3mL and, therefore, the box has 180mL Then, the total quantity would be 180 mL, but the total days supply would remain the same 14 days. |

Calculate the number of packs, the total quantity, and the total days supply for the following Rx: Albuterol 0.083% neb solution sig: 1 vial 4 x a day with 1 month supply ------------------------------------------------------------ The sig says: use 1 vial in nebulizer four times a day for 30 days So, the patient will use 1 * 4 * 30 which is 120 vials. The pharmacist will dispense Albuterol Sulfate Inhalation Solution 0.083% with 25x3mL unit-dose vials. This Albuterol pack has 25 vials and, thus, the number of packs to be dispensed will be 120 vials divided by 25 vials which is 5 packs. This pack has 25 vials and each vial has 3 mL and, in turn, 25 * 3 = 75 mL So, each pack has 75 mL If 1 pack = 75 mL, then 5 packs = 375 mL So, the total quantity to be dispensed will be 375 mL Now, the total days supply is 30 days as stated by the doctor. On the other hand, some pharmacists will dispense Albuterol Sulfate Inhalation Solution 0.083% with 60x3mL unit-dose vials. This Albuterol box has 60 vials. In this case, the pharmacist would dispense two boxes of 60 vials each, that is, 120 vials. Now, each vial has 3 mL and, therefore, 120 vials * 3 mL = 360 mL Then, the total quantity would be 360 mL and the total days supply would remain the same 30 days. It is worth noting that, for this prescription, most pharmacists would prefer to dispense 2 boxes of 60 vials rather than 5 boxes of 25 vials. |

Calculate the number of packs and the total quantity for the following Rx: Albuterol 0.083% solution 2.5 mg/3 mL sig: tid prn 30 days ------------------------------------------------------------ The doctor has prescribed Albuterol Sulfate Inhalation Solution 0.083%, 2.5mg/3mL with 25x3mL unit-dose vials. The sig says: use 1 vial via nebulizer three times daily as needed for 30 days So, the patient will use 1 * 3 * 30 which is 90 vials. This Albuterol pack has 25 vials and, thus, the number of packs to be dispensed will be 90 vials divided by 25 vials which is 4 packs. We know that each pack has 25 vials and each vial has 3 mL and, therefore, the pack has 25 * 3 which is 75mL If 1 pack = 75 mL, then 4 packs = 300 mL So, the total quantity on the pharmacy computer will be 300mL and the number of boxes dispensed will be 4 boxes of 25 vials each. |

Calculate the total quantity and the total days supply for the following Rx: albuterol solution 0.042% sig: 3 mL q4h disp: 1 box ------------------------------------------------------------ The doctor has prescribed albuterol sulfate inhalation solution 0.042% (this medicine can also be written as albuterol sulfate 1.25mg/3mL inhalation solution) The sig directions say: use 3 mL every four hours On the other hand, we need to rewrite the sig directions in order to make them easier for the patient to understand. So, let's first look at the following: This medicine comes in a carton. The carton contains 30 single vials. Each vial contains 3 mL of solution, that is, 1 vial = 3 mL Now, the final sig will say: use 1 vial in nebulizer every four hours The doctor wants the pharmacist to dispense one box. We know that each box contains 30 vials. In turn, 30 vials * 3 mL = 90 mL and, therefore, each box contains 90 mL So, the total quantity to be dispensed will be 90 mL Now, we need to calculate the total days supply. We know that the patient uses 1 vial every four hours, that is, the patient uses 1 vial six times daily. In other words, the patient uses 6 vials per day. We also know that the box to be dispensed contains 30 vials. So, the total days supply will be 30 vials divided by 6 vials which is 5 days. It is worth noting that AccuNeb 1.25mg/3mL is the brand name while albuterol sulfate 1.25mg/3mL is the generic name. It is also worth noting that a box of albuterol sulfate 1.25mg/3mL inhalation solution is supplied in two sizes: either 25 vials or 30 vials In turn, some pharmacists may dispense the box of 25 vials. If the pharmacist dispenses the carton of 25 vials, then the total quantity would be 75mL because 25 vials * 3 mL equal 75 mL and, in turn, the total days supply would be 25 vials divided by 6 vials which is 4 days. |

Calculate the total quantity and the total days supply for the following Rx: albuterol sulfate 1.25mg/3mL disp: 1 month supply sig: uad in nebulizer prn for difficulty breathing ------------------------------------------------------------ The sig says: use as directed in nebulizer as needed for difficulty breathing The doctor has prescribed albuterol sulfate 1.25mg/3mL inhalation solution. This medicine can also be written as albuterol sulfate 0.042% This medicine comes in a carton. The carton contains 30 single vials. Each vial contains 3 mL of solution and therefore 30 vials * 3 mL = 90 mL So, the carton has 90 mL The doctor says for the pharmacist to dispense one month supply. In this case, the pharmacist will dispense one carton. So, the total quantity to be dispensed is 90 mL The total days supply is 30 days as stated by the doctor. It is worth noting that some pharmacists may want to dispense two cartons. If the patient gets only one carton, then the carton may not last 30 days. So, dispensing two cartons is probably the right choice, but the final decision is up to the pharmacist. It is worth noting that AccuNeb 1.25mg/3mL is the brand name while albuterol sulfate 1.25mg/3mL is the generic name. It is also worth noting that a box of albuterol sulfate 1.25mg/3mL inhalation solution is supplied in two sizes: either 25 vials or 30 vials |
